INTRODUCTION
We present here the 3D digital models of five isolated teeth (Fig. 1; Table1) documenting two distinct fossil Cebidae: Cebussp., a medium-sized capuchin (Cebinae) and Cebuella sp., a tiny marmoset (Callitrichinae). The fossils were recently discovered in Peruvian Amazonia (Contamana, Loreto Depart-ment) from fluvial deposits (CTA-43) dating from the early late Miocene (ca. 11 Ma; i.e., Mayoan South American Land Mammal Ages [SALMA]; Antoine et al., 2016). They were recovered after wet-screening of about 800 kg of sediment. The material documenting Cebus sp. is a single lower m1 (Fig. 1A), lacking its entire buccal margin (about four-fifths of the crown are preserved). Cebuella sp. is documented by three premolars (one lower p4, one half P3 or P4, and one upper P2; Fig. 1B-D, respectively) and one particularly worn upper incisor (I2; Fig. 1E). Although limited, this new fossil material of platyrrhine primates is particularly critical because it testifies of the first and oldest records of the modern Cebuellaand Cebus/Sapajus lineages in the lower latitudes of the Neotropics. This discovery has therefore substantial macroevolutionary implications about the origin of extant marmosets and capuchins, and it implies significant changes regarding their historical biogeography (see Marivaux et al., 2016).
METHODS
AVIZO 7.1 (Visualization Sciences Group) software was used for visualization, segmentation and 3D rendering. The teeth were prepared within a “labelfield” module of AVIZO, using
Model IDs Taxon Description
MUSM-3243 Cebussp. Left lower m1 (lingual part)
MUSM-3239 Cebuellasp. left lower p4 MUSM-3240 Cebuellasp. right upper P3 or P4
(buccal part) MUSM-3241 Cebuellasp. right upper P2 MUSM-3242 Cebuellasp. upper I2

the segmentation threshold selection tool. The 3D models are provided in .ply format, and then can be opened with a wide range of freeware.
ACKNOWLEDGEMENTS
3D data presented in this work were produced through the technical facilities of the Montpellier RIO Imaging (MRI) platform and of the LabEx CeMEB. We particularly thank R. Lebrun (ISE-M, Universit´e de Montpellier) for his help and advices during micro-CT scan acquisitions and treatments. This work (paleontological fieldwork and laboratory post-field analyses) was financially supported by the L. S. B. Leakey Foundation. This work has also benefited from an “Investisse-ments d’Avenir” grant managed by the Agence Nationale de la Recherche, France (CEBA, ANR-10-LABX-0025-01).
